Question

我有一个问题，我有一个列表View可以称之为ListView1，它是从Azure同步后从本地存储动态填充的。

现在我在选择并从项目点击中获取信息时遇到问题我需要获取四种不同类型的信息，并在列表视图中有项目点击时将其传递给弹出窗口。

//This is the way the List is Created
string DB_PATH = Path.Combine(ApplicationData.Current.LocalFolder.Path, "my.db");

    public async void CreateList ()
    {
        await AzureWebService.Instance.InitLocalStoreAsync(DB_PATH);
        var t = await AzureWebService.Instance.GetListItems(); //GET THE OG LIST

        var list = new ObservableCollection<winMerchant>(); //create a new list of Names, (with the BitmapImage Field )

        foreach (var f in t)
        {
            var m = new winDirectory(); //give the customized merchant object, the same VALUES as the ACTUAL mercahnt object

            m.MyName1 = f.MyName1;
            m.MyName2 = f.MyName2;
            m.MyNumber = f.MyNumber; //int 
            m.MyPic = ImageHelper.Base64StringToBitmap(f.MyPic); //CUSTOM PART ==> Take the newly defined BitmapImage (wMyPic) and convert the Pic string into it

            list.Add(m); //add the new People into a list

        }
        MyList.ItemsSource = list;         
    }

这就是xaml

<ListView.ItemTemplate>
    <DataTemplate>

        <StackPanel Orientation="Horizontal" VerticalAlignment="Center" HorizontalAlignment="Stretch">

            <Image Source="{Binding wPic}" Width="75" Height="75" />

            <StackPanel Orientation="Vertical" VerticalAlignment="Center">

                <TextBlock Text="{Binding wMyName1}" />
                <TextBlock Text="{Binding wMyName2}" />

            </StackPanel>
        </StackPanel>

    </DataTemplate>
</ListView.ItemTemplate>

助手类

class winMerchant: Contacts
{
    public   BitmapImage wPic { get; set; }

    public int wMyNumber { get; set; }

    public string wMyName1 { get; set; }

    public string wMyName2 { get; set; }
}

点击时应将数字传递给弹出窗口... 任何帮助都感激不尽！

Answer 1

尝试添加

AutomationProperties.Name="{Binding wMyNumber}" to the <Image>

通过这个你可以传递被点击的对象的数量，在c＃（点击事件内）你可以创建一个List＆lt;＆gt;或者包含有关对象数据的数组（这样您就可以使用此对象集合在弹出按钮中显示它）

Answer 2

您可以从ListView的项目点击事件中获取所选项目的编号。

private void MainListView_ItemClick(object sender, ItemClickEventArgs e)
    {
        var item = e.ClickedItem as winMerchant;
        int number = item.wMyNumber;
    }

同时使ListView的IsItemClickEnabled =“True”。
